Method Summary

Modifier and Type	Method	Description
boolean	addAllowed()	Answer true iff Graph.add(org.apache.jena.graph.Triple) can be used to add at least some triples to the graph.
boolean	deleteAllowed()	Answer true iff Graph.delete(org.apache.jena.graph.Triple) can be used to remove at least some triples from the graph.
boolean	handlesLiteralTyping()	Answer true iff this graph compares literals for equality by value in find() operations, rather just applying RDFTerm equality.
boolean	sizeAccurate()	Answer true iff Graph::size() is accurate.

sizeAccurate

public boolean sizeAccurate()

Description copied from interface: Capabilities

Answer true iff Graph::size() is accurate.

Specified by:

sizeAccurate in interface Capabilities

addAllowed

public boolean addAllowed()

Description copied from interface: Capabilities

Answer true iff Graph.add(org.apache.jena.graph.Triple) can be used to add at least some triples to the graph.

Specified by:

addAllowed in interface Capabilities

deleteAllowed

public boolean deleteAllowed()

Description copied from interface: Capabilities

Answer true iff Graph.delete(org.apache.jena.graph.Triple) can be used to remove at least some triples from the graph.

Specified by:

deleteAllowed in interface Capabilities

handlesLiteralTyping

public boolean handlesLiteralTyping()

Description copied from interface: Capabilities

Answer true iff this graph compares literals for equality by value in find() operations, rather just applying RDFTerm equality. Only applies to GraphMem. TDB models have this effect because of canonicalization for certain datatypes and ranges, SDB models don't.
